Simplified motor brake

摘要: A motor brake mechanism (10) includes retaining structure (46) permitting removal and replacement of friction discs (16, 18) without disassembling the mechanism. When is detached from motor, a single bolt permits radial discs. Minimizing drag enabled by adding low force compression springs (162, 164, 166, 168, 170, 172) otherwise modifying which prevents rotation pressure plates (38, 40) relative to end plate (28) (10), wherein first set studs (42, 44, 46) provide both functions non-rotatably mounting springs, all separate another (70, 72) lever (68) (28). The solenoid (104) mounted on (122, 124) resilient shock absorbers (126, 128, 130, 132) perform dual absorbing mechanical plunger (106) at its travel stroke minimizing buzz. latter function provided in conjunction with simplified nut(148, 150) adjustment abutment surface (120). Separate cover are eliminated, (98) same (70 mount (68). Improved pivot bearings hardened drive pins (64 66) providing substantially point contact facilitating smooth pivotal bearing movement manual release (182) spacer (206) accommodating two 18).
